The kinase is a trimer and there are 3 "correct answers" to this
docking problem.

This benchmark case is special. Because the alignments below
align only the residues visible in the
electron densities, you cannot see that there is a stretch of 9
residues missing in BOTH bound and unbound
structures 1KKL_A and 1JB1_A. We recommend modeling them in for
best docking results.

NOTE THAT IN THE ALIGNMENTS BELOW, GAPS MOST LIKELY INDICATE
RESIDUES MISSING IN THE ELECTRON DENSITY.
